三门峡水电站300kN回转吊的设计

Design on 300kN rotating crane of sanmenxia hydropower station

回转吊受力较为复杂,设计计算时容易混淆力的性质,对杆件计算时存在少算漏算现象。本文以三门峡300KN回转吊为例,按回转机构、变幅机构分类设计。实践表明,计算分析结果可以作为结构强度评估和结构优化设计的可靠依据,为大型回转吊结构的安全可靠性分析提供了可借鉴的经验。

Load types can not be clearly divided because load is complicated in design and computation of rotating crane.Less computation and omission of the loads of pole exist.As an example by 300kN rotating crane,rotating and amplitude machines are computed.The results have been applied to rotating crane optimized design and manufacture.Its operation experience shows that the results can provide reasonable data for the crane optimized design and also can be an illustration of the estimation of structural integralit...
